The hair color change in newborns occurs from the first days of birth. Intrauterine hairs are no longer needed by the baby. Their function is complete.
The old ones will fall out, new ones will appear with one color or another, depending on the dominant gene. The number of hairs will decrease up to 3-4 months. In six months, the hair will become sore dense, not as soft in sensations as it was after birth.
After the first year, a radical restructuring of the hairline takes place:
- If a baby is genetically destined to be a dark brunette, he will darken even more than during childbirth.
- If you are told to be blond, the child will be born light, by the age of one it will become even lighter.
The hair color of a newborn change: from 0 to 3-4 months, from 5 to 12 months, from 1 to 2 years.
Remember hair color does not affect its health. The hair you get today could not be yours forever. Your kid grows and develops from the small toe to the hair follicle every day.
Changing a baby’s appearance can sometimes be very frustrating.
When does the baby change their hair color?
Some babies will always have black hair while others will change to brown or some other color like blonde.
The age that your baby’s hair changes color is different for everyone. Most babies that are born with black hair will lose their black hair and start growing blonde hair at about two years old.
Remember– Hair color Changes Throughout Life!
Natural processes, hair dye, or hair treatments cause hair color changes throughout life.
A person’s hair color is determined by the amount of melanin in the hair.
Melanocytes are the cells responsible for pigment production. Melanocytes activate to produce more pigment in response to a stimulus of more sun exposure, pregnancy hormones, or hormones produced by an overactive pituitary gland.
Natural processes of ageing can cause some people to have less pigment in their hair, making it lighter over time. We call this greying and usually starts with the temples and then percolates through the rest of the scalp.
Hair dye is one way that people change their hair color with no chemical processes that would affect it naturally. You can use hair dyes on darker shades of natural black or brown.
When my baby inherits my hair color!
It’s not that easy to predict what color hair your baby will have. Genetics are complicated! Your baby can inherit any of the three genes that cause hair color from each parent.
Furthermore, the genes are dominant or recessive, so it’s hard to predict what color your baby’s hair will be even if you know the colors of their parent’s hair.
Some babies have brown eyes because both parents have brown eyes. But for your child to have brown eyes too, both parents must pass on a gene for brown eyes and nobody else in the family would carry a gene for blue or green eyes.

The science behind the hair color genetics
When can parents determine their baby’s hair color?
The answer lies in genetics.
While genes determine your child’s hair color, the specific combinations of genes that your child inherited from you and his/her other parent can influence the shade of their hair color.
There are 3 types of hair color:
- Black hair,
- Brown/Red hair,
- Blonde/White hair
Blonde and white hair is a recessive trait that is defined as a lack of pigment in the hair shafts. The addition of two copies of this gene will give you blonde or white hair. The brown and red gene has a dominant phenotype, so if you have one copy of this gene, it will express itself as brown or red and any other color genes that you might have inherited from your parents.
When Can I tell if the baby hair color changes?
With your baby’s hair, it’s difficult to tell if it has changed. It is possible that he or she grew darker hair because of natural processes. It’s also possible that the color was light, to begin with, but has since deepened.
When does baby hair texture change?
A baby’s hair texture changes with time. It starts off as straight, then it is curly or wavy, and finally it becomes more unruly.
Procedures and science behind the baby hair texture work!
Hair texture is a measure of how tightly curled hair strands are. Hair fibers that curl tightly towards the head, such as Afro hair, are naturally curly and have a coarse texture. Hair fibers that curl away from the head, such as Caucasian hair, are straight and have a finer texture.
The outer layer of coarse hair fibers forms tighter curls when subjected to more tension during their growth cycle than fine fibers. Coarse textures absorb water easily, making them prone to frizzing in damp environments, but fine textures do not absorb as much water as coarser ones. This can be helpful for stopping your hair from getting wet iron-shaped after swimming.
When does baby hair texture change: The phases of baby hair change?
As babies grow, their hair changes texture and length. There are three phases of baby hair change –
- During the first phase, the baby has soft, fluffy hair.
- The second phase is known as the “ratty” phase because of how messy it looks.
- And finally, in the third and final phase (known as the “silky” stage) their hair will be sleek and shiny again.
Final Verdict
The hair color of a newborn change from 0 to 3 months, from 5 to 12 months, and 1 to 2 years. This is because the baby’s hair grows in first, and then the color develops. You should contact your pediatrician if you think your baby has been injured. Or if you notice any other changes in their behavior.
